There is no data-at-rest encryption in Managed clusters built-in, except that Dynatrace encrypts sensitive data such as credentials inside the Cassandra database. We recommend to use transparent disk encryption, such as dm-crypt software or self-encrypting drives, or - if used in the cloud - make use of block storage encryption (e.g. AWS EBS to encrypt disks).
Backups are also not encrypted by Dynatrace and also rely on the mentioned encryption techniques.
